AIR-SPRING BOTTOM FOR BEDS.

SPECIFICATION forming part of Letters Patent No. 362,532, dated May10,1887.

Application filed February 17, 1887. Serial No. 227,939. (No modcl.l

To all whom, it may concern:

Be it known that I, LEMUEL PATTERSON, a citizen of the United States,residing at Olean, in the county of Oattaraugns and State of New 5 York,have inventeda new and useful Improvement in Air-Spring Bottoms forBeds, of which the following is a specification.

The invention relates to improvements in air-spiing bottoms for beds,sofas, and lounges;

IO and its objects are to provide a bottom that will be sufficientlyelastic to conform to the body and be comfortable to a person lying inany position, that will be coolin warm weather, and upon which amattress can be placed in 1 cold weather to render the bed sufficiently.warm. These objects I accomplishby means of the construction andcombination of the devices hereinafter described, pointed out in theclaim, and illustrated in the accompanying 2o drawings, in which- Figure1 represents a central longitudinal section of a bed-bottom in which theinvention is embodied. Fig. 2 represents a transverse section of thesame on the lines or x of Fig. 1..

Fig. 3 represents a detail view, in vertical 1011- gitudinal section, ofthe means whereby the air is pumped intothe device.

Referring to the drawings by letter, A designates a hollow rectangularframe, consisting 0 of the Vertical sides and end pieces, a a, and thebottom board, B, firmly and rigidly secured to the said piece by screwsor nails, which pass through the re-enforcing strips a a below thebottomboard and enter the lower edges of the If preferred, the frame Amay be made of plate metal. The said frame is designed to restupon twoor more slats of a bedstead or within a suitable frame of a lounge orsofa.

o The frame A is covered within with cloth or paper, orboth, preferablyarranged in a suitable number of continuouslay ers, forming alining,b,secured bycement or otherwise to the bottom and sides of the frame. Thelayers are each 5 coated with a size or paint, that will render themair-tight and will at the same time bind them together,and thelining,when so formed, is covered well with the same material. I havefound that glue and nolassesmixed in proper 5o proportions makeadesirable size for this purpose. The paint or size used should have aexternally with the same size or paint, and

having its edges secured air-tight to the upper edges of the pieces a bymeans of the strips 0 and nails, screws, or other suitable means, thus vforming, with the frame A, the air-space D.

E is the air-condensing-puinp,by means of which the airspace D isfilled, consisting of the cylinder 6, piston-rod, and piston e, properlypacked to work air-tight in the cylinder, as shown in Fig. 3.

The cylinder is secured to the under surface of the bottom board, 13,and its inner end turns upward at right angles and is flanged, as shown,to adapt it to be secured by screws passing through openings in saidflange to the base-board B around the opening F therein. The cylinder isprovided nearits outer or-open end with the openings f f for theentrance of air before the piston.

G is an upwardly-opening platevalve hinged or pivoted on one side of theopening F to a valve-seat, g, the circular opening of which registerswith the said opening.

H is a vertical 'rod with its head resting on 8 5 the upper surface ofthe valve G, thencepassing through the valve and through the verticalpart of the cylinder 6, and having upon its threaded end, outside of thesame, the thumbnut h. 0

The manner of forcing the air into the air space D is apparent from theforegoing description. WVhen the said space has received sufficientair,the thumb-nut is turned up so as to force the valve G down upon itsseat and 5 prevent any leakage at that point. To introduce more air thenut is turned down. i

A great advantage of the described bed-bottom is that the top only isflexible and elastic material, so that there is much less surface liableto rupture, and, as the bottom and sides are of rigid and unyieldingmaterial, the flexible top is better sustained and its edges are keptalways in the same position.

Any desired ornamental cover can be placed over the top 0, and amattress will rest easily 5 thereon on account of its rigid bottom andsides.

Having described my invention, 1 claim- The herein-described improvementin airbeds, comprising the bed having the rigid IO bottom board providedwith the opening F, the cylinder E, secured to the under side of thebottom board, provided with perforations fat one end, and having itsother end turned up and communicating with the opening F, the piston e,Working in the cylinder, and the valve G, hinged upon the bottom boardto one side of the opening F and closing the same, and a stem dependingfrom said valve through the cylinder, substantially as specified.

In testimony that I claim the foregoing as my own I have hereto affixedmy signature in presence of two witnesses. I

LEMUEL PATTERSON.
